Answer: 38.3 lbs
Explanation:
First, we will find how many grams the books are. To do this, we will multiply the 12 books by the 1,450 grams per book.
12 * 1,450 = 17,400 grams
Next, we will change 17,400 grams into kilograms using 1 kilogram = 1,000 grams.
17,400 grams = 17.4 kilograms
Then, we can change these kilograms into pounds using 1 kilogram = 2.2 pounds. Lastly, we will round to the nearest tenth of a pound.
17.4 kilograms = 38.28 pounds ≈ 38.3 lbs
